Shadrap Posted April 4 Posted April 4 What variety of stone would you recommend for the separate oxidizers and fuels to be ground with? I have 3-4 different mortar and pestle combinations to use and the are mostly granite or marble mineral based. Does the fuel need to be possibly ground with a ceramic mortar to really ensure no possibility of sparking or host stone contamination? I have properly seasoned and internally polished all my mortars buy hand with salt and rice ground for about an hour each. Just curios about the details, thanks.
Zumber Posted April 6 Posted April 6 Whats wrong with grinder? I grind oxidizers using common coffee grinder except hygroscopic oxidizers. I dont ever grind /mill fuels. 1
